plant named ‘AKIV5-4’

Abstract

A new and distinct cultivar of Verbena plant named ‘AKIV5-4’, characterized by its upright and outwardly spreading plant habit; vigorous growth habit; freely branching habit; freely flowering habit; dark red-colored flowers that are held above and beyond the foliage; and resistance to Powdery Mildew.

Description

Botanical designation: Verbena hybrida.

Cultivar denomination: ‘AKIV5-4’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Verbena plant, botanically known as Verbena hybrida, and hereinafter referred to by the name ‘AKIV5-4’.

The new Verbena plant is a product of a planned breeding program conducted by the Inventor in Shiga, Japan and Bonsall, Calif. The objective of the breeding program is to create new semi-upright Verbena cultivars with attractive flowers and resistance to Powdery Mildew.

The new Verbena plant originated from a cross-pollination made by the Inventor on Apr. 5, 2005 in Shiga, Japan of a proprietary selection of Verbena hybrida identified as code number VJ05-13-1, not patented, as the female, or seed, parent with a proprietary selection of Verbena hybrida identified as code number 04V73-01, not patented, as the male, or pollen, parent. The new Verbena plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Bonsall, Calif. on Jun. 30, 2006.

Asexual reproduction of the new Verbena plant by terminal cuttings in a controlled environment in Bonsall, Calif. since Jul. 3, 2006 has shown that the unique features of this new Verbena plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Verbena have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘AKIV5-4’. These characteristics in combination distinguish ‘AKIV5-4’ as a new and distinct cultivar of Verbena:

• • 1. Upright and outwardly spreading plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Freely flowering habit.
  • 5. Dark red-colored flowers that are held above and beyond the foliage.
  • 6. Resistant to Powdery Mildew.

Plants of the new Verbena can be compared to plants of the female parent selection. Plants of the new Verbena differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Verbena are more upright than plants of the female parent selection.
  • 2. Plants of the new Verbena have larger flowers than plants of the female parent selection.
  • 3. Plants of the new Verbena are more resistant to Powdery Mildew than plants of the female parent selection.

Plants of the new Verbena can be compared to plants of the male parent selection. Plants of the new Verbena differ primarily from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Verbena are more freely flowering than plants of the male parent selection.
  • 2. Flowers of plants of the new Verbena are longer lasting than flowers of plants of the male parent selection.
  • 3. Plants of the new Verbena have shorter peduncles than plants of the male parent selection.

Plants of the new Verbena can be compared to plants of the Verbena hybrida ‘KLEI04077’, disclosed in U.S. Plant Pat. No. 17,905. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Verbena differed primarily from plants of ‘KLEI04077’ in the following characteristics:

• • 1. Plants of the new Verbena had darker green-colored leaves than plants of ‘KLEI04077’.
  • 2. Plants of the new Verbena were more freely flowering than plants of ‘KLEI04077’.
  • 3. Flowers of plants of the new Verbena were longer lasting than flowers of plants of ‘KLEI04077’.
  • 4. Plants of the new Verbena and ‘KLEI04077’ differed in flower color.

Plants of the new Verbena can also be compared to plants of the Verbena hybrida ‘USBENAL17’, disclosed in U.S. Plant Pat. No. 14,877. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Verbena differed primarily from plants of ‘USBENAL17’ in the following characteristics:

• • 1. Plants of the new Verbena were not as trailing as plants of ‘USBENAL17’.
  • 2. Plants of the new Verbena had shorter peduncles than plants of ‘USBENAL17’.
  • 3. Plants of the new Verbena and ‘USBENAL17’ differed in flower color.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following description were grown under conditions which closely approximate commercial production conditions during the autumn in 12.5-cm containers in an outdoor nursery in Bonsall, Calif. During the production of the plants, day temperatures ranged from 18° C. to 38° C., night temperatures ranged from 9° C. to 18° C. and light levels ranged from 7,000 to 10,000 foot-candles. Plants were pinched one time and were six weeks old when the photographs and description were taken.
